' ink UNITED STATES PATENT OFFICE THOMAS H. WOOD, OF NEW YORK, N. Y.,ASSIGNOR TO J. B. BREWSTER & 00., OF SAME PLACE.

IMPROVEMENT lN CARRIAGE-SPRINGS.

Specification forming part of Letters Patent N 0. 139,348, dated May 27,1873; application filed I January 6, 1873.

To all whomgit may concern:

Be it known that I, THOMAS H. WOOD, in the city, county, and State ofNew York, have invented a new and useful Improvement in Light Carriages,of which the following is a specification Figure 1 is the side elevationof a vehicle with the near wheels removed. Fig. 2 is a plan view of mysupporting-frame with the box or buggy-body resting thereon.

Similar letters of reference indicate corresponding parts.

This invention relates to an improved arrangement of transverse springson light wagons, and has for its object to combine, in a wagon supportedon single transverse springs and side bars, the advantage of elasticity,double elliptic transverse springs, and of the deep setting of the bodyobtained at present by using the single springs. Light carriagessupported on double elliptic springs raise the bodies too high forconvenience, and are moreover more expensive than those having singlesprings. On the other side such carriages as are at present supported onsingle transverse springs, whose ends connect with side bars rigidlysecured to the wagon-bodies, are not sufficiently elastic and yieldingto suit the rapid motion to which they are frequently subjected. Theinvention consists in the improvement of light vehicles, as hereinafterdescribed and pointed out in the claim.

elasticity they may possess, in making the support of the body Ayielding. To the under side of the carriage body A are securedtransverse springs G G, whose ends connect, by

suitable couplings, with the side bars F F, as v is clearly shown in thedrawing. The springs G G and E E can be made of metal or wood or othermaterial, and are semi-elliptic or flat springs in contradistinctiontothe full elliptic spring heretofore used as direct supports forcarriage bodies on their axles.

Having thus described my invention, 1

claim as new and desire to secure by Letters Patent Afra'me, consistingof the longitudinal side bars F F, downwardly-bowed end springsE E, andupwardly-bowed middle springs G G, constructed, arranged, and applied asand for the purpose described.
